So my water keeps from going clear to hazy and dull and occasionally cloudy. My water had been clear all season except for at opening in May. Ever since Fathers Day weekend it keeps going from clear to hazy/cloudy and I can get it clear again but days later just goes back. The only difference since Fathers day is we got a dolphin escape and it does work great but you can see paths it makes where it is dirty. I use the fine filter as well but I do think it kicks alot up. We had a bad storm Fathers day weekend and that's the same day I got the dolphin and the next day this all started. I posted a week ago about this mystery dirt/pollen that keeps collecting on the pool floor every morning. Every morning I find piles of mystery dirt on the edges of my pool. Ive tried skimmer socks and they turn yellow and do collect a bunch of dirt but it is still everyday dealing with this and my water isn't how it use to be. I have kept my chlorine at a 7 consistently for 2 weeks Ive been testing the chlorine 3 times a day and adding liquid chlorine only and really even on a sunny day only lose at the most 2ppm. I did 2 OCLT last week and passed. I was bad and tried clarifier thinking if it was pollen maybe it would help and it did for 4 days then went back looking weird. I backwashed 3 days ago and my backwash was green. I am fed up with the way the water looks and started a slam lastnight. I slammed to 16 and was a 13.5 this morning with 0.5cc. I had to work a 12 hr shift today but my husband added more chlorine and used the dolphin to clean the mystery dirt or now algae. By the time I had come home at 7 the mystery dirt already returned and that never happens. We brushed and it was kicking up green clouds. The water did look more clear this evening though. So this has to be algae right? Im thinking maybe it just hasn't turned green because I havent let my fc get too low? We do have alot of trees and I find pollen flakes from catkins in the pool but it seems to be leaning more on algae now. My question is would it be best to use either my cordless vaccuum during the slam or vaccuum to waste? Or can I use my dolphin? If I vaccuum to waste I will need to add more water since I just backwashed 3 days ago and we haven't had any rain. I plan on taking my ladder out tomorrow and cleaning it out. What is the best way to clean the inside? Also do I need to clean my kids pool toys and floats during the slam and how do I do that??? I just want my clear sparkling water back
